Please help its 7to10 please as fast as possible I wanna sleep

7. 2b and b are like terms, and 3 are like terms

8. 6 and 7 are like terms, 2n and are like terms

9. m and 2m are like terms, 3³ and 2 are like terms

10. 6³ and 6² are like terms, y³ and 5y³ are like terms

Step-by-step explanation:

Let us solve from No. 7 to No. 10

#7

∵ The terms are 2b, , b, , 3, 2x²

∵ 2b and b have the same variable and the same power

∴ 2b and b are like terms

∵ and 3 have same variable b and same power 6

∴ and 3 are like terms

#8

∵ The terms are 6, 2n, 3n², 6m², , 7

∵ 6 and 7 are numerical rational terms

∴ 6 and 7 are like terms

∵ 2n and have the same variable and the same power

∴ 2n and are like terms

#9

∵ The terms are 10k², m, 3³, , 2m, 2

∵ m and 3m have the same variable and the same power

∴ m and 2m are like terms

∵ 3³ and 2 are numerical rational terms

∴ 3³ and 2 are like terms

#10

∵ The terms are 6³, y³, 3y², 6², y, 5y³

∵ 6³ and 6² are numerical rational terms

∴ 6³ and 6² are like terms

∵ y³ and 5y³ have the same variable and the same power

∴ y³ and 5y³ are like terms

14

step-by-step explanation:

14 x 3 = 42

the answer is 1030 it's very simple math.
